Abstract
An object of the present invention is to provide an optical film having an optically-anisotropic layer having excellent durability, a polarizing plate and an image display device in which the optical film is used, a polymerizable compound used in the optical film, and a method for manufacturing a 1,4-cyclohexanedicarboxylic acid monoaryl ester. The optical film of the present invention is an optical film having at least an optically-anisotropic layer, in which the optically-anisotropic layer is a layer obtained by polymerizing a polymerizable liquid crystal composition containing a polymerizable compound which has a specific structure, a liquid crystal compound which has a specific structure, and a polymerization initiator.
